FIRE-EXTINGUISHING APPARATUS.

SPECIFICATION forming part 0f Letters Patent N0. 739,327', dated September 22, 1903.

Application filed September 13, 1902. Serial No. 123,242. (No model.)

ratuses, of which the following is a specifica.-

tion.

This invention relates to fire-extinguishing apparatuses; and it consists in certain improveniente in the constructionv thereof, as will be hereinafter fully described, and pointed out in the claims. u l i The invention is illustrated inthe accompanying drawings, as follows:

l Figure l shows a section on the line l l in Fig. 2. Fig. 2 shows a front elevation of the apparatus. Fig. 3 showsa sectionon the line 3 3 of the fragile cap and mechanism incident thereto.

A marks the inlet-passage. nected with the fire-extinguishing-duid supply, preferably steam.

Extending from the passage A isla flange a, and secured to this flange is the flange b2 of the fragile cap B. The fragile cap forms a closure for the passage A. It has the a-nnular groove b, which decreases the thickness of the cap to such an extent that it may be readily broken by transverse pressure exerted at the outer end of the cap. An inclosing means C is also secured to the flanges o, and b2. and forms a housing for the cap B. This inclosing cap or means has the opening c. A small piece of pipe E rests' on-the end of the cap B and extends up through this opening. The outer end of 'the c ap B is provided with a slot b'. A rod D extends through the pipe E and slot b and rests in the socket C' at the bottom of the inclosing cap C. The rod D forms a guide for a weight F. The Weight F is normally held in its upper position by means of the chain G. A trip-lever I is ar-` This is conp on the pipe E, exerts sufficient strain on the end of the cap B 4to break it along the annular groove b. The action of steam upon the cap B forces it into the upper part of the cap C and out of the main passage of steam. The moving steam holds the cap B in this upward position. The slot b',eugaging the rod D, prevents a forward movement of the cap B, and thus avoids the clogging oftne passage. by such action.

Secured to the incjlosingvcap O is a distributing system consisting of the pipe L and the nozzles Z. This distributing system may be as extensive as desired. Immediately adjacent to the cap O is a lwhistle-pipe M, 'on which is attached a Whistle N, the extended pipe on the system L exerting sufficient back pressure tosound the alarm through the whistle N.l In case of fire, the weight being released, as above stated, the cap B is broken and forced out of the way of the moving steam steam passes into the pipe L, blows the Whistle, and is distributed by means of the nozzles Z.

v What I claim as new isl. In Ya nre-extinguishing apparatus the combination of the passage for conveying reextinguishingmaterial; a fragile cap for said passage; and inclosing means for said fragile cap; distributing means leading from said inclosing means; devices for `breaking said fragile cap; and means acting with a predetermiued temperature for setting said devices in motion.

2. Inv a tire-extinguishing apparatus the combination of the passage for conveying fireextinguishing material; a fragile cap for said passage, said'cap having a line or part of suficientweakness to determine the line of fracture; devices for breaking said fragile cap;

and means acting with a predetermined temperature for setting said devices in motion.

In a fire-extinguishing apparatus the combination with a Apassage for conveying iirefextinguishiug material; a fragile cap for said passage said cap havinga part of sufii- Ico predetermined temperature for setting said devices in motion.

4. In a fire-extinguishing apparatus the combination of a passage for conveying lireextinguishing material; a fragile cap for said passage; an inclosing means for said fragile cap, saidinclosing means and fragile cap being arranged to effect a movement of the fragile cap incident to the iiow of steam out of the line of passage; devices for breaking said cap; and means acting with a predetermined temperature for setting said devices in motion.

5.' In a fire-extinguishing apparatus the combination of a passage for delivering reextinguishing material; a fragile cap for closing said passage; and an inclosing means for said cap, said means being arranged t0 retain the fragments of said fragile cap when broken; and means for acting with said inclosing means, and the cap for preventing the fragments of the cap from clogging the passage.

G. In a fire-extinguishing apparatus the` combination of the passage A; of the cap B having the annular groove b and slot d; the inclosing means C having the opening c; the pipe E arranged in the opening c and resting upon the cap B; the rod D extending through the pipe E and slot b; the weight F arranged 3o on the rod D; and means for releasing the weight F with a predetermined temperature.

7. In a fire-extinguishing apparatus the combination of the passage A; of the cap B having the annular groove b and slot d; the 35 inclosing means C having the opening c; the pipe E arranged in the opening c and resting upon the cap B; the rod D extending through the pipe E; a connection on the inclosing means C leading to the whistle-pipe M; and 4o said whistle N.

8. In a fire-extinguishing apparatus the combination of the passage A; of the cap B having the annular groove b and slot d; the inclosing means C having the opening c; the 45 pipe E arranged in the opening c and resting upon the cap B; the rod D extending through the pipe E and slot b; the weight F from the predetermined pressure; the pipe L secured in the inclosing means C; and the nozzlesl 5o on the pipe L.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
